when i installed Linux, appeared Incorrect Communications:
Linux installation freezes upon start-up, when installing Linux on a machine that is more than a few years old. i try to fix for this problem is to boot the machine and press the button that brings up the BIOS screen (usually one of the F-numbered keys). Locate and select the option to disable plug-and-play support on the screen, and then restart the installation. Once Linux is successfully installed, re-enable the plug-and-play support. But it is not working.
